FLOOR AND CEILING CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 719,380, dated January 27, 1903.

Application filed March 20, 1902. fierial No. 99,231. (No model.)

To all whom it may concern: ets D, preferably of a U shape, passing there- Be it known that I, JACOB SCHRATWIESER, through and having ends D turned outwardly a citizen of the United States, and a resident and then upwardly to pass underneath and of Brooklyn, in the county of Kings, city and through the metal lath C. It will be observed 5 State of New York, haveinvented certain new that where perforated metal lath is used the and useful Improvements in Floor and Ceilupturned end D may be passed through any ing Constructions, of which the following is one of the perforations thereof. In the modia specification. fication of the bracket shown in Fig. 3 the My invention relates particularly to a concross-piece is provided with a notch A in its 10 struction adapted to be placed between the upper edge and the bracket is passed over the joists or I-beams of a building and to support cross-piece through the notch, so that it will the fioorsandceiling. Its objects, among othnot be accidentally displaced. Rods 13 exers, are to provide a light, strong, and durable tend transversely of the cross-pieces and are structure of this character of a simple and insupported by being passed therethrough; but

15 expensive construction, the parts of which these rods may be made in the form shown in may be made outside of the building in which Fig. 4, consisting of three pieces, the hangthey are to be used and taken to the said ers B and the cross-rods B passing through building and assembled with a comparatively the hangers. These hangers are preferably small amount of manual labor. passed through notches in the upper edge of 20 It consists of the combination and arrangethe cross-pieces in a manner similar to the ment of parts hereinafter described and brackets D. If desired, the hangers B may claimed, and illustrated in the accompanying be extended downwardly a suitable distance drawings referred to herein. to receive rods B passed therethrough for In the said drawings, Figure 1 is a vertical the purpose of supporting the ceiling.

25 section at right angles to the I-beams of a I have provided for the support of the ceilfloor and ceiling construction embodying my ing clips or brackets E, consisting of a double improvements. Fig. 2 is a sectional detail of hook formed of wire, band-iron, or the like, the bracket D, adapted to support the edges havingits ends E passed through the lath and of the sheet-metal lath or other material, over the lower flanges of the I-beams. The

30 shown by dotted lines, used to form the botportion E intermediate the two ends is then tom or base upon which the concrete is suptwisted to form a loop through which the rods ported on the line 2 2 of Fig. 1. Fig. 3 is a E upon which the ceiling is supported, may like view of a modification. Fig. 4. is a modibe passed. fication of the bracket D. Fig. 5 is a detail In order to separate the cross-pieces A and 5 of my separator. Fig. 6 is a detail plan View hold them securely in position, I have proof the overlapping corrugated terminals of the vided a separator, (shown in Fig. 5,) which cross-pieces. consists of a single piece of metal F, having The cross-piece A extends from beam to its'ends F turned over and mortised. These beam and has its ends notched out to receive mortises F are then placed over the upper 0 the flange thereof. These ends A are prefedges of the cross-pieces, and the tendency of erably corrugated, and the extreme end of the folded or doubled portion to expand will each cross-piece A is turned or curled outform a secure grip to hold the same in posiwardly to form a flange which will rest upon tion. The lower part of the I-beam is incased the flange of the I-beam and prevent the crossin sheet-metal lath c, which is supported by 5 piece from tilting. The corrugated ends of having its upper edges 0 turned around two the cross-pieces A are fitted together and seof the rods B, and the space between the beam cured by a rivet or other suitable means. The and casing is filled with concrete or other suitcross-pieces are provided with perforations able filling. The sheet-metal lath c rests upon A, which allow the concrete to unite therethe transverse rods B and has its edges sup- 50 through. They are also provided with brackported by the brackets D.

What I claim is- 1. The combination with the beams of crosspieces extending from beam to beam, separating-strips resting upon said cross-pieces and comprising strips of metal having their ends upset or turned over and recesses in said ends alined and adapted to receive the upper edges of the cross-pieces.

2. The combination of cross-pieces, beams supporting the same, separating bars or strips connecting said cross-pieces and composed of strips of metal having their ends turned over, recesses in the turned-over portion of each strip and in the body thereof, the said recesses being alined and adapted to receive the upper edges of the cross-pieces.

3. The combination with the beams of crosspieces supported thereby, and corrugated overlapping ends of said cross-pieces.

4:. The combination of beams, cross-pieces supported thereby,.corrugated ends on said cross-pieces; the same being fitted and secured together.

5. The combination of beams, cross-pieces supported thereby,and outwardly-turned terminals on said cross-pieces resting edgewise upon the said beams.

6. The combination with I-beams of cross pieces supported thereby, rods connecting said cross-pieces,sheet metal extending around the lower portion of said beams and supported to receive brackets, brackets supported by said cross-pieces and extending downwardly from the point of support, portions on said brackets extending outwardly therefrom and sheet metal having its edges upon the said extended portions.

8. In combination with the beams, crosspieces supported by the same, brackets having depending portions supported by the said cross-pieces, upturned ends of the said brackets and perforated sheet metal having the said upturned ends entering the perforations thereof.

9. The combination with beams of crosspieces supported thereby, rods passing through the said cross-pieces,sheet metal supported by the said rods between the crosspieces and also extending around the lower flanges of the said beams and concrete supported by said sheet metal surrounding the beams.

10. The combination of beams, cross-pieces supported thereon, and strips or bars connecting the said cross-pieces; the said strips or bars being formed of a continuous piece of metal having its ends upset or turned and mortises in the two thicknesses of the turned portion adapted to receive the said crosspieces.

Witness my hand, this 12th day of March, 1902, at the city of New York, county and State of New York.
